IMPORTANT SAFETY INSTRUCTIONS

When using this electrical equipment, basic safety precautions should always be followed, includ-

ing the following:

• READ AND FOLLOW ALL INSTRUCTIONS

• WARNING: Risk of Electric Shock. Connect controller only to a grounding type recep-

tacle protected by a ground-fault circuit interrupter (GFI). CAT Controllers recommends

installation to a dedicated GFI circuit breaker performed by a licensed electrician.

• WARNING: Disconnect power before servicing. Other than the fuses, there are no user

serviceable parts inside the controller.

• WARNING: All power cords should be inspected frequently. Any damaged power cords

must be replaced immediately to reduce the risk of electric shock. Never operate a

controller without functional ﬂow protection.

• WARNING: Installation requires a properly located GFI protected receptacle. Never use

an extension cord for electrical connections to the controller.

• WARNING: Always mount controller in a safe area not subject to damage by moving

objects. Never bury controller power cords.

• WARNING: Any person using, adjusting, or monitoring the controller must be at least 18

years of age and be familiar with these instructions and the contents of this manual.

• WARNING: Always take and record manual water chemistry readings in conformance

with Health Department requirements. Although automated controllers are a great aid in

maintaining healthy water quality, controllers are not a substitute for manual water test-

ing with an accurate test-kit.

• WARNING: Always read and become familiar with Material Safety Data Sheets (MSDS)

and safe handling instructions for all chemicals used with the controller.

• CAUTION: The automatic controller should not be installed where it is accessible to the

public.

Introduction

Description

The CAT 4000 revolutionizes the manner in which water quality can be monitored and maintained.

A pool operator typically checks, records and adjusts pool or spa water chemistry hourly at best.

The CAT 4000 continuously samples pH and sanitizer activity, adjusting the feeding of chemicals

on a basis proportional to the demand. Hourly water quality readings are sent along with any

alarms or service requests through a wireless network to the POOLCOMM web server for remote

monitoring and management through any internet connection. NOTE: The POOLCOMM website is

a subscription based service. Monthly charges apply.

From the website, the subscriber can monitor water quality, print charts, graphs and logs, change

controller settings, and designate contacts for outbound notiﬁcation via email, cell phone or PDA.

Optional digital ﬂow and level sensors are available to monitor ﬂow rate, chemical storage tank

levels, and even automate water level control.

The results include elimination of “human error”, accurate and reliable maintenance of chemical

levels twenty-four hours a day, compliance with Health Department operating standards, reduced

burden on operating staff, and a reduction of chemical usage and costs. The CAT 4000 control-

ler and POOLCOMM water quality management website together provide unprecedented control,

access and documentation.

What’s Included

Description

The following is a description of the components incorporated in a typical CAT 4000 wireless water

quality control system:

The Professional-Series pH Sensor samples water from the ﬁltration system and sends signals to

the controller indicating the acidity of the water. The ideal pH range for pools and spas is 7.4 - 7.6.

The CAT 4000 controller is preset from the factory to maintain pH 7.5. If pH is maintained below

7.4 (too acidic), eye irritation, corrosion of equipment, and damage to the pool or spa surface can

occur. If pH is maintained above 7.6 (too alkaline), sanitizer activity is reduced, water may become

cloudy, and eye irritation may result.

The Professional-Series ORP Sensor samples water from the ﬁltration system and sends signals

to the controller indicating the oxidation-reduction potential (redox) of the water. ORP is an actual

measure of sanitizer activity (chlorine, bromine, ozone, etc.) and bacteriological water quality rather

than an expression of chemical residual levels. The CAT 4000 controller is preset from the factory

to maintain ORP at 650 millivolts.

The Flow Sensor monitors the rate of ﬂow across the pH and ORP sensors and signals the control-

ler to disable automated chemical feeding during periods when the ﬁltration system is off or low

recirculation ﬂow is detected.

The Flow Cell provides a convenient location for mounting the pH, ORP and Flow sensors while

ensuring ideal hydraulic conditions to maximize sensor performance and life.

The CAT 4000 Controller scans and interprets the signals from the pH, ORP, ﬂow, and optional

digital ﬂow-rate and level sensors, displays water quality readings and alarms in alphanumeric

format, and activates chemical feeders in proportion to demand to maintain pH and ORP setpoint

levels.

The controller incorporates audible and visual safeguard alarms for out of range conditions and

menu-driven control of setpoints, alarms, and a host of advanced features. The CAT 4000 control-

ler also features an internal transceiver for wireless transmission of data between the controller

and POOLCOMM website.

The Level Sensors (optional) provide signals to the controller indicating low pH chemical tank level,

low ORP tank level, and low water level.

The Digital Flow Sensor (optional) provides a ﬂow rate to be displayed by the controller and an

alarm indication when ﬁlter maintenance is required.

Installation

Installation Procedure

The key to a successful ﬂow cell installation is in the plumbing. A pressure differential is required to

allow clean, untreated water to pass through the cell and across the sensors. We recommend using

the enclosed tubing and ﬁttings to create a pressure-suction “loop” line.

Follow the directions below for installation and refer to the Installation Diagram on page 6.

1. Turn off heater, chemical feeders, pump, and any other related equipment. Relieve pressure

from ﬁltration system.

2. Select a convenient mounting location for the controller unit which will meet the following

criteria:

• Facilitates a combined (inﬂuent and efﬂuent) maximum tubing run of 30’

• Located a minimum of ten feet from pool or spa

• GFI protected power source available

• Easily accessible to pool or spa operator

• Away from corrosive materials and physical hazards

3. Securely mount PVC Backboard on vertical wall.

4. Drill and tap a 1/4” NPT port at a location just downstream of the ﬁlter, but upstream from

any chemical injection point. Install a tubing connector, and run ﬂex tubing to the inﬂuent

ﬂow cell port.

5. Drill and tap a 1/4” NPT port at a location subject to vacuum or reduced pressure. Install the

remaining tubing connector and run ﬂex tubing to the efﬂuent ﬂow cell port.

6. Cut a 3” length of ﬂex tubing and insert into the sample stream port.

USE ONLY HAYWARD GENUINE REPLACEMENT PARTS

7. Remove pH and ORP sensors from the plastic storage bottles and save bottles and storage

ﬂuid for future use. Thread sensors into ﬂow cell.

8. Remove BNC protective covers from left side of controller unit and store for future use.

These covers protect the controller unit from electrostatic discharge (ESD) and should be

used whenever handling or transporting the controller unit.

9. Connect the pH, ORP and Flow sensor cables to the controller unit as labeled. Sensor cables

are constructed from a specialized material - never cut or splice.

10. If new or additional chemical feeders are to be used with the controller, install according to

manufacturer’s instructions at this time.

11. Connect chemical feeders to the controller as labeled (See diagram on following page).

12. Check all electrical and mechanical connections. Resume ﬁltration system operation and

check for any leaks.

Pool Chemistry

Now that your new controller has been physically installed, water chemistry should be tested and

adjusted prior to initiating automated control of the pool or spa. Conﬁrm that your pool or spa water

conforms to the following ranges before powering on and setting up the CAT 4000.

The table below indicates generally accepted guidelines. Always maintain water chemistry accord-

ing to standards set by your local or State Health Department.

Test Minimum Ideal Maximum

pH 7.2 7.5 7.8

Free Chlorine (PPM) 1 2 3

Bromine (PPM) 2 3 4

Cyanuric Acid (PPM) 0 - 100

ORP (mV) 650 - -

Total Alkalinity 80 - 120

Calcium Hardness 200 - 400

All CAT water quality controllers maintain sanitizer levels (chlorine, bromine, ozone, etc.) based

on ORP. Although ORP is a superior index of water quality compared to part per million sanitizer

residual levels, factors such as pH, cyanuric acid concentration and total dissolved solids can affect

sanitizer residual readings relative to ORP.

CAT Controllers recommends establishing desired pH, sanitizer residual, calcium hardness, total

alkalinity, temperature and cyanuric acid levels prior to initiating automated control of the pool or

spa. The ORP setpoint will need to be changed periodically as described later in this section if the

goal is to provide consistent sanitizer residual levels rather than consistent control of ORP.

Conﬁguration

Overview

The CAT 4000 features a bright, menu-driven vacuum-ﬂuorescent display which makes setup and

programming simple in any lighting conditions. The menu structure is divided into two sections; the

Operating Menu is intended for the end user to manage settings which are accessed on a frequent

basis, while the Conﬁguration Menu is used to set up advanced features which truly customize the

controller to meet the individual requirements of the application.

The keypad provides intuitive access to the controller functionality as described on the following

page.
